How Can Vaughan Help You


Exploded View

Vaughan chopper pumps and Triton screw centrifugal pumps are available in several configurations and sizes to suit most needs for agricultural, municipal and industrial processing applications. Durability and performance are critical in any application. Vaughan flow rates range from 50 to 12,000 USGPM and we use only the toughest materials (ductile iron, hardened steel, high chrome iron, 316 stainless steel and CD4MCu hardened stainless steel) to keep the system running right. All Vaughan chopper pumps include a written Performance Guarantee - your assurance of clog-free operation.

Standard delivery is 4 to 6 weeks, and, when you need them, all parts are readily available from stock for expedited delivery.

Vaughan Reliability: Agricultural Application

Cattle Dairy

Jim Vaughan invented the first chopper pump back in 1960, after working on local dairymen's pumps in his repair shop and realizing the need to "chop" the solids while pumping. Since then, Vaughan chopper pumps have been successfully applied on dairies where high reliability and low maintenance are demanded. Applications for Vaughan chopper pumps on dairies included:

  • Barn Flush Pit
  • Separator Feed
  • Lagoons
  • Digester Mixing
  • Scraped Manure

Over the years, Vaughan has introduced a series of unique pump configurations specialized for the agricultural industry, including vertical wet well, submersible, dry well pumps.

Unmanned Floating Platform

The FP26 Unmanned Floating Platform is designed for lagoon maintenance, dewatering, field irrigation, or sludge removal. Any Vaughan Vertical Wet Well pump can be mounted onto the platform, depending on the requirements. Foam filled polyethylene pontoons are weather and water resistant. Optional controls, hoses, sludge manifolds and winching systems are available.

Turbo Agitator

The Turbo Agitator is a directional mixer for sludge pits, designed to efficiently rotate the contents by pulling settled sludge from the bottom and redirecting flow horizontally, causing a circular rotation within the pit. Available with grease pack bearings or oil bath mechanically sealed bearings.

Vaughan Reliability: Municipal Application

From treatment plants to hospitals, Vaughan Pumps are the most reliable option to keep the water flowing.

Clarifier Scum

Triton Screw

Vaughan Pumps handle both primary and secondary clarifier scum without plugging or air binding. The optional recirculator is available for both the Vertical Wet Well or Submersible pumps for large pits, or pits with long retention times, to allow pre-mixing of the stratified scum prior to pumpout. The oil bath bearing system allows complete pumpdown of the scum on each cycle.

The Vaughan Vertical Recirculator Chopper Pump is the most popular for clarifier scum pits, allowing complete mixing of the pit to put floating solids back into suspension. For total automation, the recirculator valve can be motor operated with timers, allowing the pump to recirculate the pit for a pre-set amount of time prior to pumpout.

Digester Scum Blanket

Anaerobic digesters are notorious for the formation of scum blankets due to grease, hair and other floatables. The Vaughan Scumbuster® virtually eliminates the effects of a scum blanket and prevents it from reforming by homogenizing and conditioning. This type of mixing allows digesters to regain their design capacity, extends the time between cleanouts and generates more methane gas.

Anaerobic Digester Mixer

The Scumbuster with a 20 HP, 1750 RPM Explosion Proof motor will handle most digesters up to 80 feet in diameter. Larger diameter digesters, or heavy scum blankets, may require 2 pumps. The model 5300 will fit a 28” minimum diameter manhole, and the 4900R will fit a 24” diameter manhole. The Scumbuster consists of a recirculator nozzle assembly with all gas-tight fittings through a custom deck plate to match the existing manhole, a heat treated impeller and cutter bar, epoxy paint, a zinc anode for cathodic protection, an intrinsically safe oil monitor relay and a neoprene mounting gasket.

Digester Mixing

Vaughan Pumps effectively mix digester sludge, replacing gas, draft tube, submersible prop, or other pump mixing systems, while increasing digester efficiency by continuously chopping solids without the need for expensive pre-grinders or comminutors. Vaughan's 8"- 16" pumps produce volumes up to 8000 GPM.

Digester Recirculation

Vaughan Chopper Pumps effectively recirculate digester sludge through heat exchangers, increasing digester efficiency while eliminating clogging of the heat exchanger and the need for expensive pre-grinders or comminutors.

Lift Stations

Raw incoming solids are chopped and pumped dependably with Vaughan Chopper pumps, replacing standard non-clog pumps and eliminating the need for expensive pre-grinders or comminutors in troublesome sewage applications - especially prisons, hospitals, restaurants and other institutional and public facilities.


Raw concentrated solids from septic tanks create a severe pumping environment for standard sewage pumps. Rags and plastics can clog solids handling type pumps.

Sludge Transfer

Vaughan Chopper Pumps handle up to 18% solids in municipal sludge. The chopping action eliminates roping caused by the wrapping of hair and rags due to pre-rotation of recessed impeller pumps.

Vaughan Reliability: Industrial Application


Vaughan pumps are so strong and reliable that they can be used in nearly any application. Here are just a few of the ways customers have used our pumps and systems.

Automotive / Steel

Vaughan Pumps set the standard in strength and reliability. By utilizing the toughest materials available our pumps can be used in virtually any application, no matter how abrasive or demanding.


  • Paint overspray sludge
  • Chrome based painting slurries
  • Body metal, glass and plastic
  • Mineral and oil washdown
  • Boiler blowdown
  • Coke breeze
  • Coke tar decanter sludge
  • Iron ore pellets
  • Mill scale
  • Rolling grinder cooling water

Chemical / Petrochemical

Suspended solids in chemical production and waste treatment create highly corrosive and abrasive pumping conditions.


  • Detergent cakes
  • Hand cleaners with pumice
  • Latex skins
  • Lead oxide slurries
  • Paint sludges
  • Plastics
  • API separators
  • Coke slurries
  • Oil waste
  • Refinery mud
  • Storm drains

Contractor Services

Industrial and hazardous waste solids suspended in chemical solutions create the worst environment for any pump. Lagoon cleaning, sludge dewatering and storage tank cleaning all require dependable pumping equipment to handle unknown plastics, glass and metals.


  • Hazardous waste cleanup
  • Lagoon cleaning
  • Recycled solvents
  • Sludge dewatering
  • Storage tank cleanout

Food Processing

Vaughan pumps are ideally suited for waste handling in all types of food processing, including restaurants, poultry, pork, beef, fish, fruit and vegetable processing.


  • Blood and bones
  • Vegetables such as carrots, corn husks, potatoes and tomatoes
  • Poultry feathers, whole chickens and turkeys
  • Seafood Processing waste

Rendering operations including:

    • Fleshings and pieces of hide
    • Offal
    • Horns, Hooves, ears, fat and hair

Institutional & Correctional

Vaughan Chopper Pumps are ideally suited for institution and correctional facility pumping stations. The combination of chopping and pumping eliminates plugging on rags, clothing, bedsheets, towels, blankets, plastics and other stringy materials. Vaughan pumps can directly replace existing pumps, eliminating the need for a pre-grinder or comminutor.


  • Sewage lift stations
  • Kitchen waste

Mining / Sand & Gravel

Extremely abrasive environments are detrimental to conventional sleeve bearings, packing and lip seals. Vaughan's unique seal-and-bearing design with the patented seal shroud addresses these problems. Heat treatment of wear parts extends pump life, while minimizing maintenance costs.


  • Acid mine water
  • Coal and sand washing
  • Concrete batch plant sumps
  • Sand and gravel silt ponds
  • Truck washdown sumps


Paper & Wood Products

Vaughan pumps ability to handle the high solids’ content and the combination of abrasive and corrosive materials in contaminated wastewater make them ideal for the pulp and paper industry.
